How is a multitarget stool DNA test sample collected?

• A. Blood sample
• B. Urine sample
• C. Saliva sample
• D. Full stool sample in provided kit

Answer: (D)

A multitarget stool DNA test looks for specific DNA changes in DNA shed by colorectal cells that end up in stool. Because these biomarkers come from the lining of the colon and are present in the solid stool, the sample must be collected as a full stool specimen using the kit’s collection container. The kit also provides a preservative to stabilize the DNA during transport, ensuring accurate testing. Blood, urine, or saliva do not contain the colorectal DNA markers the test analyzes, so they aren’t suitable for this assay. Using a provided stool collection kit guarantees the lab receives an appropriate, preserved sample from which the DNA markers can be reliably detected.
